Bassist Jaco Pastorius was probably the most famous user of Acoustic bass amplifiers, using two 360/361 units onstage. Pat Metheny used the Acoustic 134 model combo guitar amplifier. Canadian guitar virtuoso Frank Marino used the 270 model amplifier as did Frank Zappa Pete Townsnsendand Ernie Isley. Albert King and Chuck Berry also used the 260 and 261. Krieger's Acoustic amps were a major public-relations boost for the fledgling company. Robby Krieger, guitarist of The Doors was the most high-profile early user of the Acoustic 260 head and 261 cabinet-the first models ever produced by ACC. Jimmy Nolen of James Brown's band was also a 'Black Widow' user.

One prolific user associated with this guitar was jazz guitarist Larry Coryell who had an endorsement deal. The majority of the guitars were built in Japan although Semi Moseley (of Mosrite fame) claims of building the last 200 guitars made. The guitars and basses were based on designs used by Paul Barth for his Bartell guitars and basses. Acoustic also produced the 'Black Widow' electric guitar and electric bass 1972 - 1975. The company is remembered in particular for its Acoustic 361 bass stack, consisting of an Acoustic 360 bass pre-amplifier and one or two Acoustic 361 W-bins, each featuring a built-in 200-watt RMS power amplifier and a rear-facing 18' Cerwin-Vega loudspeaker. Most of the amplifiers produced by ACC were solid-state, but a few models later in production were valve amps. Its original location was a shack on Sunset Boulevard in Los Angeles, California.

Acoustic Control Corporation was a manufacturer of instrument amplifiers, founded by Steve Marks (with the help of his father) and based in Van Nuys, California.
